Aqualung looked beyond pleasure divers and focused in on tech divers when designing the Teknika Mask. Its design and construction would make almost any tech diver weep with joy. (It`s ok we won`t tell anyone!) The Teknika is a Two-Window Mask that is constructed with a Shock Absorbent Techno-Polymer Outer Frame and is assembled with Stainless Steel AISI 304 Bolts and Screws. This Mask was built to take the Hard Knocks Experienced by Gear owned and used by Tech Divers, but it isn`t just about being strong. The Teknika is also a Comfortable Mask to Wear. The Black Silicone Rubber Double Feathered Edge Skirt and Wide Split Style Mask Strap combine to create a Perfect Seal on the Face. The Teknika Mask and its Silicone Strap means it will stay in place without causing the Mask to Bite into your Face. It`s Double Jointed Buckles Rotate Vertically-and-Horizontally and has Quick Adjust Push-Buttons to give you the Perfect Fit. The Teknika`s crowning feature is its ability to fold, which makes stowing it in a BCD pocket a breeze. Mask is equipped with an Easy-to-Reach One Handed Nose Pocket for Ear Equalization which can be utilized even when wearing thick gloves. The Dual Lenses are Tempered Glass for a Great View and the Low Profile, Low Internal Volume Design makes it easy to clear. Mask comes in Black only includes a Protective Mask Box for Safe Storage and is covered by a 24 month limited warranty.
